I am in the same boat, looking to 10X my effort. 

Some deals are gone in a day, others take time and work to develop, but if someone is willing to put the effort in there are plenty of deals out there.

I don't blame them and it's not worth the time/effort/cost to sue the previous owner over a statement that (frankly) is impossible to prove.

It has not made an effort to get into the middle of the autonomous vehicle race.

If I fail in my initial efforts to approach PMs and LLs on my short list of target properties (these are very small neighborhoods), then I've decided to go with some combination of advertising and direct mail.

Also there is generally some wording at the end that is something like "While we have made a best effort we cannot see behind walls/panels etc so get each system inspected individually".

While a little more headache up front to setup and some ongoing maintenance efforts the income is way larger which help the NOI (which push the value up) and the owner can also depreciate the costs of the machines and write off the expenses of the normal maintenance costs.

If I am personally signing on a note, I am comfortable in the 50% to 80% levered position, and make sure that I have enough positive cash flow (cash on cash return) to make it worth my effort, depending on property type/location etc.

@David LaukaThere's been some buzz about revitalization efforts there.

Depending on exactly the situation, the investor may be willing to pay you some money for your efforts as they may then be able to get title to the property more quickly and avoid court costs.
